Sorry, missed the initial post, so replying to a reply.

Linux has supported the BCM54616 PHY since April 2015. If the Intel
drivers used the Linux PHY drivers, you would not of had this problem.

It would be good if somebody spent the time to migrate these MAC
drivers to use the common Linux PHY infrastructure.
